1.2.1 Physical Characteristics As shown in Figure 1, the ST 800 is packaged in two major assemblies: the Electronics Housing and the Meter Body. The elements in the Electronic Housing respond to setup commands and execute the software and protocol for the different pressure measurement types. Figure 2 shows the assemblies in the Electronics Housing with available options. The Meter Body provides connection to a process system. Several physical interface configurations are available, as determined by the mounting and mechanical connections, all of which are described in the “Installation” section of this manual.

Page 2 ST 800 SmartLine Pressure Transmitters User’s Manual Revision 5.0

Figure 1 – ST 800 Major Assemblies

Figure 2 – Electronics Housing Components

1.2.2 Functional Characteristics Functionally, the Transmitter can measure process pressure and provides a proportional analog 4 to 20 mA output to the measured process variable (PV). Available output communication protocols include Honeywell Digitally Enhanced (DE), HART, and FOUNDATION Fieldbus. An optional 3-button assembly is available to set up and make adjustments to the Transmitter. In addition, a Honeywell Multi-Communication (MC) Toolkit (not supplied with the Transmitter) can facilitate setup and adjustment procedures. Certain adjustments can be made through an Experion Station or a Universal Station if the Transmitter is digitally integrated with Honeywell’s Experion or TPS/TDC 3000 control system.


1.3 ST 800 Transmitter Name Plate The Transmitter nameplate mounted on the bottom of the electronics housing (see Figure 1) lists its model number, physical configuration, electronics options, accessories, certifications, and manufacturing specialties. Figure 3 is an example of a typical Gauge Pressure (GP) or Atmospheric Pressure (AP) Transmitter name plate. The model number format consists of a Key Number with several table selections. The Differential Pressure (DP), Absolute Pressure (AP), and Gauge Pressure (GP) name plates are essentially the same. However, the DP provides one additional entry (7 vs. 6) in the Meter Body Selections (Table I) to accommodate the static pressure rating.

Figure 3 –Typical ST 800 Name Plate

You can readily identify the series and basic Transmitter type from the third and fourth digits in the key number. The letter in the third digit represents one of these basic transmitter types: • A = Absolute Pressure • D = Differential Pressure • F = Flange Mounted • G = Gauge Pressure • R = Remote Seals For a complete selection breakdown, refer to the appropriate Specification and Model Selection Guide provided as a separate document.

1.4 Safety Certification Information An “approvals” name plate is located on the bottom of the Electronics Assembly; see Figure 1 for exact location. The approvals name plate contains information and service marks that disclose the Transmitter compliance information. Refer to Appendix C of this document for safety certification requirements and details.

1.5 Transmitter Adjustments Zero and Span adjustments are possible in ST 800 SmartLine Pressure Transmitters with the optional three-button assembly located at the top of the Electronic Housing (see Figure 2). You can also use the Honeywell MC Toolkit or other third-party hand-held zero to make any adjustments to an ST 800 SmartLine Pressure Transmitter. Alternately, certain adjustments can be made through the Experion or Universal Station, if the Transmitter is digitally integrated with a Honeywell Experion or TPS system.

2 Application Design

2.1 Overview This section discusses the considerations involved with deploying a Honeywell ST 800 SmartLine Pressure Transmitter in a process system. The following areas are covered:

• Safety • Input and output data • Reliability • Environmental limits • Installation considerations • Operation and maintenance\ • Repair and replacement

2.2 Safety

2.2.1 Accuracy The ST 800 SmartLine Pressure Transmitter (Transmitter) measures the gauge, differential, or absolute pressure of a process and reports the measurement to a receiving device. Measurements are accurate up to 0.0375 of the calibrated span.

2.2.2 Diagnostic Messages Transmitter standard diagnostics are reported in the two basic categories listed in Table 3. Problems detected as critical diagnostics drive the analog output to the programmed burnout level. Problems detected as non-critical diagnostics may affect performance without driving the analog output to the programmed burnout level. Informational messages (not listed in Table 3) report various Transmitter status or setting conditions. The messages listed in Table 3 are specific to the Transmitter, exclusive of those associated with HART and DE protocols. HART and DE diagnostic messages are listed and described in the ST 800 SmartLine Pressure Transmitter HART/DE Option User Manual, document number 34-ST-25-38.

2.2.3 Safety Integrity Level (SIL) The ST800 is intended to achieve sufficient integrity against systematic errors by the manufacturer’s design. A Safety Instrumented Function (SIF) designed with this product must not be used at a SIL level higher than the statement, without “prior use” justification by the end user or diverse technology redundancy in the design. Refer to the ST 800 & ST 700 Safety Manual, 34-ST-25-37, for additional information.


3 Installation and Startup

3.1 Installation Site Evaluation Evaluate the site selected for the ST 800 Transmitter installation with respect to the process system design specifications and Honeywell’s published performance characteristics for your particular model. Some parameters that you may want to include in your site evaluation are: • Environmental Conditions:

o Ambient Temperature o Relative Humidity

• Potential Noise Sources: o Radio Frequency Interference (RFI) o Electromagnetic Interference (EMI)

• Vibration Sources o Pumps o Motorized System Devices (e.g., pumps) o Valve Cavitation

• Process Parameters o Temperature o Maximum Pressure Rating

3.2 Honeywell MC Toolkit In preparation for post-installation processes, refer to the MC Tookit User Manual, Document # 34-ST-25-20, for battery conditioning and device operation and maintenance information.

3.3 Display Installation Precautions Temperature extremes can affect display quality. The display can become unreadable at temperature extremes; however, this is only a temporary condition. The display will again be readable when temperatures return to within operable limits. The display update rate may increase at cold temperature extremes, but as with readability, normal updating resumes when temperatures are within limits for full operability.


3.4 Mounting ST 800 SmartLine Pressure Transmitters

3.4.1 Summary Transmitter models, except flush mounts and those with integral flanges, can be attached to a two-inch (50 millimeter) vertical or horizontal pipe using Honeywell’s optional angle or flat mounting bracket; alternately you can use your own bracket. Flush-mount models are attached directly to a process pipe or tank by a one-inch weld nipple. Models with integral flanges are supported by the flange connection. Figure 4 shows typical bracket-mounted and flange-mounted transmitter installations.

Figure 4 – Typical Bracket Mounted and Flange Mounted Installations

3.4.2 Mounting Dimensions Refer to Honeywell drawing number 50049930 (Dual Head), 50049931 (In-Line), 50049932 (Flange Mount) 50049933 (Extended Flange), and 50049934 (Remote Seal) for detailed dimensions. Abbreviated overall dimensions are also shown on the Specification Sheets for the transmitter models. This section assumes that the mounting dimensions have already been taken into account and the mounting area can accommodate the Transmitter.


3.4.3 Bracket Mounting Procedure If you are using an optional bracket, start with Step 1. For an existing bracket, start with Step 2.

1. Refer to Figure 5. Position the bracket on a 2-inch (50.8 mm) horizontal or vertical pipe, and install a “U” bolt around the pipe and through the holes in the bracket. Secure the bracket with the nuts and lock washers provided.

Figure 5 – Angle Mounting Bracket Secured to a Horizontal or Vertical Pipe

2. Align the appropriate mounting holes in the Transmitter with the holes in the bracket. Use the bolts and washers provided to secure the Transmitter to the bracket; see the following variations.

3. Loosen the set screw on the outside neck of the Transmitter one (1) full turn.

4. Rotate the Electronics housing a maximum of 180o left or right from the center to the position you require, and tighten the set screw 8.9 to 9.7 pound-inches (1.40 to 1.68 Newton meters), using a 4mm metric socket head wrench. See the following example and Figure 7.

EXAMPLE: Rotating the Electronics Housing

Figure 7 – Rotating the Electronics Housing

The mounting position of absolute pressure models STA822, STA82L, or a draft range model STD810 is critical as the Transmitter spans become smaller. A maximum zero shift of 2.5 mmHg for an Absolute Transmitter or 1.5 inches of water (inH2O) for a Draft Range Transmitter can result from a mounting position that is rotated 90o from the vertical. A typical zero-shift of 0.12 mmHg or 0.20 inH2O can occur for a five (5)-degree rotation from the vertical.


3.4.4 Mounting Transmitters with Small Absolute or Differential Pressure Spans

To minimize positional effects on calibration (zero shift), take the appropriate mounting precautions for the respective Transmitter model. For a model STA822 or STA82L, ensure that the Transmitter is vertical when mounting it. You do this by leveling the Transmitter side-to-side and front-to-back.

3.4.5 Flange Mounting Figure 9 shows a typical tank-flange mount installation, with the Transmitter flange mounted to the pipe on the wall of the tank.

On insulated tanks, remove enough insulaiton to accommodate the flange extension. When flange-mounting to a tank, note the following:

• The End User is responsible for providing a flange gasket and mounting hardware suitable for the Transmitter service conditions.

• To avoid degrading performance in flush-mounted flanged Transmitters, exercise care to ensure that the internal diameter of the flange gasket does not obstruct the sensing diaphragm.

• To prevent performance degradation in extended-mount flanged Transmitters, ensure that sufficient clearance exists in front of the sensing diaphragm body.

Figure 9 – Tank-Flange Mounted Transmitter


3.4.6 Flush Mounting Procedure

After the Transmitter is mounted, the Electronics Housing can be rotated to the desired position. For insulated tanks, remove enough insulation to accommodate the mounting sleeve and/or the flange extension.

Mount the Transmitter flanges within the limits Table 4 for the fill fluid in the capillary tubes, with a tank at one (1) atmosphere.

Figure 10 – Typical Flush and Flange Mounted Installations

1. Refer to Figure 10 for a representative flush-mounted Transmitter installation. Cut a hole for

a one (1) inch standard pipe in the tank or pipe at the Transmitter mounting site.

2. Weld the 1-inch mounting sleeve to the tank wall or to the hole you cut in the pipe.

3. Insert the Transmitter Meter Body into the mounting sleeve, and secure it with the locking bolt.

4. Tighten the bolt to a torque of 4 Nm +0.3 Nm (4.7 pound-feet +0.2 pound-feet).


3.4.7 Remote Diaphragm Seal Mounting Information

The combination of tank vacuum and high pressure capillary head effect should not exceed nine (9) psi (300 mmHg) absolute. For insulated tanks, be sure to remove enough insulation to accommodate the flange extension. The end user is responsible for supplying a flange gasket and mounting hardware suitable for the service condition of the Transmitter.

Mount the Transmitter flanges within the limits in for the fill fluid in the capillary tubes, with a tank at one (1) atmosphere.

3.5 Piping the ST 800 Transmitter

3.5.1 Piping Arrangements Piping arrangements vary depending upon process measurement requirements and the Transmitter model. For example, a differential pressure transmitter comes with double-ended process heads with ¼-inch NPT connections, which can be modified to accept ½-inch NPT through optional flange adapters. Gauge pressure transmitters are available with various connections for direct mounting to a process pipe. A ½-inch, schedule 80, steel pipe is commonly used for Transmitter integration into a process system. Many piping arrangements use a three-valve manifold to connect the process piping to the Transmitter. A manifold makes it easy to install and remove or re-zero a Transmitter without interrupting the process. A manifold also accommodates the installation of blow-down valves to clear debris from pressure lines. Figure 12 represents a typical piping arrangement using a three-valve manifold and blow-down lines for a differential pressure transmitter being used to measure flow.

Figure 12 – Typical 3-Valve Manifold with Blow-Down Piping

3.5.2 Suggestions for Transmitter Location Suggests connections based on what is being processed by the system.

Blow-Down Piping


1. For liquid or steam, the piping should slope a minimum of 25.4 mm (1 inch) per 305 mm (1 foot).

2. Slope the piping down toward the Transmitter if it is below the process connection to allow the bubbles to rise back into the piping through the liquid.

3. If the transmitter is located above the process connection, the piping should rise vertically above the Transmitter. In this case, slope down toward the flow line with a vent valve at the high point.

4. For gas measurement, use a condensate leg and drain at the low point (freeze protection may be required here).

3.5.3 General Piping Guidelines • When measuring fluids that contain suspended solids, install permanent valves at regular

intervals to blow-down piping.

• Blow-down all lines on new installations with compressed air or steam, and flush them with process fluids (where possible) before connecting these lines to the Transmitter Meter Body.

• Verify that the valves in the blow-down lines are closed tightly after the initial blow-down procedure and each maintenance procedure thereafter.

3.5.4 Procedure to Install Flange Adapters The following procedure provides the steps for removing and replacing an optional flange adapter on the process head.

This procedure does not require that the Meter Body be removed from the Electronics Housing. If flange adapters are being replaced with parts from other kits (for example, process heads), follow the procedures for the kits and incorporate the following procedure.

NOTE: The threaded hole in each Flange Adapter is offset from center. To ensure proper orientation for re-assembly, note the orientation of the offset relative to each Process Head before removing any adapter.

Figure 13 – Flange Adapter Removal and Replacement

Refer to the instructions included with the kit for removal and replacement procedures.


3.6 Wiring a Transmitter

3.6.1 Overview The transmitter is designed to operate in a two-wire power/current loop with loop resistance and power supply voltage within the operating range shown in Figure 14.

Figure 14 – Transmitter Operating Ranges

Loop wiring is connected to the Transmitter by simply attaching the positive (+) and negative (–) loop wires to the positive (+) and negative (–) terminals on the Transmitter terminal block in the Electronics Housing shown in Figure 15.

As shown in Figure 15, each Transmitter has an internal terminal to connect it to earth ground. Optionally, a ground terminal can be added to the outside of the Electronics Housing. While it is not necessary to ground the Transmitter for proper operation, doing so tends to minimize the possible effects of noise on the output signal and affords protection against lightning and static discharge. An optional lightning terminal block can be installed in place of the non-lightning terminal block for Transmitters that will be installed in an area that is highly susceptible to lightning strikes.

Wiring must comply with local codes, regulations and ordinances. Grounding may be required to meet various approval body certification, for example CE conformity. Refer to Appendix A of this document for details.

Note: The right hand terminal is for loop test and not applicable for Fieldbus option. The Transmitter is designed to operate in a two-wire power/current loop with loop resistance and power supply voltage within the operating range; see Figure 14. With optional lightning protection and/or a remote meter, the voltage drop for these options must be added to the basic 10.8-volt supply requirements to determine the required Transmitter voltage (VXMTR) and maximum loop resistance (RLOOP MAX). Additional consideration is required when selecting intrinsic safety barriers to ensure that they will supply at least minimum Transmitter voltage (VXMTR MIN), including the required 250 ohms of resistance (typically within the barriers) needed for digital communications. Transmitter loop parameters are as follows: RLOOP MAX = maximum loop resistance (barriers plus wiring) that will allow proper Transmitter operation and is calculated as RLOOP MAX = (VSUPPLY MIN – VXMTR MIN) ÷ 21.8 mA. In this calculation:

VXMTR MIN = 10.8 V + VLP + VSM

VLP = 1.1 V, lightning protection option, LP VSM = 2.3 V, remote meter

Note that VSM should only be considered if a remote meter will be connected to the transmitter.

The positive and negative loop wires are connected to the positive (+) and negative (–) terminals on the terminal block in the Transmitter Electronics Housing. Barriers can be installed per Honeywell’s instructions for Transmitters to be used in intrinsically safe applications.

3.6.2 Digital System Integration Information Transmitters that are to be digitally integrated to Honeywell’s Total Plant Solution (TPS) system will be connected to the Pressure Transmitter Interface Module in the Process Manager, Advanced Process Manager or High Performance Process Manager through a Field Termination Assembly. Details about the TPS system connections are given in the PM/APM SmartLine Transmitter Integration Manual, PM12-410, which is part of the TDC 3000X system bookset. If you are digitally integrating a Transmitter in an Allen Bradley Programmable Logic Controller (PLC) process system, the same Field Terminal Assembly (FTA) and wiring procedures used with Honeywell’s TPS system are also used with the Allen-Bradley 1771 and 1746 platforms.


3.6.3 Wiring Variations The above procedures are used to connect power to a Transmitter. For loop wiring and external wiring, detailed drawings are provided for Transmitter installation in non-intrinsically safe areas and for intrinsically safe loops in hazardous area locations. If you are using the Transmitter with Honeywell’s TPS system, see PM/APM Smartline Transmitter Integration Manual, PM12-410, which is part of the TDC 3000X system bookset.

3.6.4 Wiring Procedure 1. See Figure 15, above, for parts locations. Loosen the end cap lock using a 1.5 mm Allen wrench.

2. Remove the end cap cover from the terminal block end of the Electronics Housing.

3. Feed loop power leads through one end of the conduit entrances on either side of the Electronics Housing. The Transmitter accepts up to 16 AWG wire.

4. Plug the unused conduit entrance with a conduit plug appropriate for the environment.

5. Connect the positive loop power lead to the positive (+) terminal and the negative loop power lead to the negative (-) terminal. Note that the Transmitter is not polarity-sensitive.

6. Replace the end cap, and secure it in place.

3.6.5 Lightning Protection If your Transmitter includes the optional lightning protection, connect a wire from the Earth Ground Clamp (see Figure 15) to Earth Ground to make the protection effective. Use a size 8 AWG or (8.37mm2) bare or green covered wire for this connection.

3.6.6 Supply Voltage Limiting Requirements If your Transmitter complies with the ATEX 4 directive for self-declared approval per 94/9EC, the power supply has to include a voltage-limiting device. Voltage must be limited such that it does not exceed 42 V DC. Consult the process design system documentation for specifics.

3.6.7 Process Sealing The ST 800 SmartLine Pressure Transmitter is CSA-certified as a Dual Seal device in accordance with ANSI/ISA–12.27.01–2003, “Requirements for Process Sealing Between Electrical Systems and Flammable, or Combustible Process Fluids.”

3.6.8 Explosion-Proof Conduit Seal

When installed as explosion proof in a Division 1 Hazardous Location, keep covers tight while the Transmitter is energized. Disconnect power to the Transmitter in the non-hazardous area prior to removing end caps for service.

When installed as non-incendive equipment in a Division 2 hazardous location, disconnect power to the Transmitter in the non-hazardous area, or determine that the location is non-hazardous before disconnecting or connecting the Transmitter wires.

Transmitters installed as explosion proof in Class I, Division 1, Group A Hazardous (classified) locations in accordance with ANSI/NFPA 70, the US National Electrical Code, with 1/2 inch conduit do not require an explosion-proof seal for installation. If 3/4 inch conduit is used, a LISTED explosion proof seal to be installed in the conduit, within 18 inches (457.2 mm) of the transmitter.


3.7 Startup

3.7.1 Overview This section identifies typical start up tasks associated with several generic pressure measurement applications. It also includes the procedure for running an optional analog output check.

Startup Tasks

After completing the installation and configuration tasks for a Transmitter, you are ready to start up the process loop. Startup usually includes:

• Checking zero input • Reading inputs and outputs • Applying process pressure to the transmitter.

You can also run an optional output check to wring out an analog loop and check out individual Process Variable (PV) outputs in Digitally Enhanced (DE) mode before startup. The actual steps in a startup procedure vary based on the type of Transmitter and the measurement application. In general, the procedures in this section are based on using Honeywell MC Toolkit to check the Transmitter input and output under static process conditions, and make adjustments as required initiating full operation with the running process. Note that like checks can be made using the optional three-button assembly, if your Transmitter is so equipped. Operation with the three-button assembly is discussed in the “Operation” section of this manual.

3.7.3 Output Check Procedures The Output Check comprises the following procedures:

• The Loop Test procedure checks for continuity and the condition of components in the output current loop.

• The Trim DAC Current procedure calibrates the output of the Digital-to-Analog converter for minimum (0%) and maximum (100%) values of 4 mA and 20 mA, respectively. This procedure is used for Transmitters operating online in analog mode to ensure proper operation with associated circuit components (for example, wiring, power supply,…, control equipment). Precision test equipment (an ammeter or a voltmeter in parallel with precision resistor) is required for the Trim DAC Current procedure.

• The Apply Values procedure uses actual Process Variable (PV) input levels for calibrating the range of a Transmitter. To measure a liquid level for example, a sight-glass can be used to determine the minimum (0%) and maximum (100%) level in a vessel. The PV is carefully adjusted to stable minimum and maximum levels, and the Lower Range Limit Value (LRV) and Upper Range Limit Value (URV) are then set by commands from the MC Toolkit.

The Transmitter does not measure the given PV input or update the PV output while it operates in the Output mode.


3.7.4 Constant Current Source Mode Procedure

Figure 16 – Current Loop Test Connections

1. Refer to Figure 16 for test connections. Verify the integrity of electrical components in the output

current loop. 2. Establish communication with the Transmitter. For these procedures, the values of components in

the current loop are not critical if they support reliable communication between the Transmitter and the Toolkit.

3. On the Toolkit, display the Output Calibration box. 4. In the Output Calibration box, select the Loop Test button; the LOOP TEST box will be

displayed. 5. Select the desired constant-level Output: 0 %, 100 %, or Other (any between 0 % - 100 %). 6. Select the Set button. A box will be displayed asking Are you sure you want to place the

transmitter in output mode?

With the Transmitter in Analog mode, you can observe the output on an externally-connected meter or on a local meter. In DE mode, you can observe the output on the local meter or on the Toolkit Monitor display.

7. Select the Yes button. Observe the output current at the percentage you selected in Step 5.

8. To view the monitor display, navigate back from the LOOP TEST display, and select the MONITOR display. A Confirm popup will be displayed.

9. Select Yes to continue. This concludes the Startup procedure.

NOTES:

Scaling only affects the value shown on the Display; it does not affect the Loop Output.

1. Linear scaling of the displayed PV value When “Linear” is selected for PV Scaling, the Display will scale the selected PV input according to the following formula:

((PV value – input low limit) / input span) x (Scaling High – Scaling Low) + Scaling Low If the PV Selection is Pressure, the input low and high limits are the LRV and URV respectively. If the PV Selection is Percent Output, the input low and high limits are 0 and 100%. If the PV Selection is Square Root, the input low and high limits are 0 and 100 %Flow. Note that this scaling only affects the value shown on the Display; it does not affect the Loop Output. 2

2. Square Root scaling of the displayed PV value

When “Square Root” is selected for PV Scaling, the Display computes %Flow from the Differential Pressure. This calculation is independent of the Transfer Function setting in the transmitter. This allows the user to output Differential Pressure via the 4-20 mA loop output while displaying the equivalent flow value on the Display. In addition, the


Display value can be scaled to show the flow in flow units (gal/min, gal/h, etc.) by entering the correct scaling limits via the Scaling Low and Scaling High parameters. For example:

PV Selection: Differential Pressure

PV Scaling: Square Root

Scaling Low: 0.0

Scaling High: 2500.0

Display Units: gal/h

LRV: 0.0

URV: set as required by the process

The Display will calculate 0-100 %Flow from the Differential Pressure and then scale this to 0 to 2500 gal/h.

Note that the Square Root calculation is referenced to the LRV and URV settings of the transmitter and its uses the LRV and URV to calculate the %DP input into the Square Root flow algorithm. For normal flow applications, it is assumed that the LRV is set to zero and that zero pressure equals zero flow. If the LRV is less than zero, the Square Root calculation will calculate the flow as bi-directional flow.

4.3 Three Button Operation with no Display Installed When there is no Display installed, the buttons can be used to perform a Zero or Span adjustment of the Transmitter. Caution should be taken to insure these adjustments are only made when the correct input pressures are applied.

4.3.1 Zero Adjustment This adjustment is the same as performing a Set LRV using the Display.

1. Connect a current meter or voltmeter as shown in Figure 16 to monitor the PV output of the Transmitter.

2. Using an accurate pressure source, apply pressure equivalent to the Transmitter LRV.

3. Press the Down (↓ ) and Zero ( ↑ ) buttons together to set the Zero.

4. Verify that the output is now 4 mA.

4.3.2 Span Adjustment This adjustment is the same as performing a Set URV using the Display.

1. Connect a current meter or voltmeter as shown in Figure 16 to monitor the PV output of the Transmitter.

2. Using an accurate pressure source, apply pressure equivalent to the desired Upper Range Value of the transmitter.

3. Press the Down (↓) and Span ( ) buttons together to set the span.

4. Verify that the PV output is now 20 mA.

You can also use the MCT 202 Toolkit to make any adjustments to an ST 800 SmartLine Pressure Transmitter. Alternately, certain adjustments are possible through an Experion Station or Universal Station, if the ST 800 is digitally integrated with either of these stations.


4.4 Changing the Default Failsafe Direction Transmitters are shipped with a default failsafe direction of upscale. This means that the Transmitter output will set the current output to upscale failsafe (maximum output) upon detection of a critical status. You can change the direction from upscale failsafe to downscale failsafe (minimum output) by moving the top jumper located in the Electronics module.

4.4.1 DE and Analog Differences Failsafe operation is somewhat different between DE and analog operation:

• Analog operation – Upscale failsafe drives the Transmitter output to 21.8 mA. Downscale failsafe drives the Transmitter output to 3.8 mA.

• DE operation – Upscale failsafe causes the Transmitter to generate a + infinity digital signal. Downscale failsafe causes the Transmitter to generate a – infinity digital signal.

The Transmitter electronics module interprets either signal as not-a-number and initiates its own configured failsafe action for the control system.

4.4.2 Procedure to Establish Failsafe Operation

The failsafe direction display accessible via the Toolkit shows only the state of the jumper as it correlates to analog Transmitter operation. Failsafe action for the DE control system may be configured to operate in a manner different from analog, as indicated by the state of the Transmitter jumper.

The integrated circuits in the Transmitter PWA are vunerable to damage by stray static discharges when removed from the Electronics Housing. Minimize the possibility of static discharge damage when handling the PWA as follows:

Do not touch terminals, connectors, component leads, or circuits when handling the PWA.

When removing or installing the PWA, handle it by its edges or bracket section only. If you need to touch the PWA circuits, be sure you are grounded by staying in contact with a grounded surface or by wearing a grounded wrist strap.

When the PWA is removed from the Transmitter, put it in an electrically conductive bag, or wrap it in aluminum foil to protect it.

The following procedure outlines the steps for positioning the write protect and failsafe jumpers on the electronics module. See Figure 18 for the locations of the failsafe and write protect jumpers.

5 Maintenance

5.1 Overview This section provides information about preventive maintenance and replacing damaged parts. The topics covered in this section are:

• Preventive maintenance of the meter body barrier diaphragms and process piping to the Transmitter.

• Replacement of damaged parts such as the Transmitter Printed Wiring Assembly (PWA) and meter body

5.2 Preventive Maintenance Practices and Schedules The ST 800 Transmitter does not require any specific maintenance at regularly scheduled intervals. However, it is recommended that you perform these typical inspection and maintenance routines on a schedule that is dictated by the characteristics of the process medium and if blow-down facilities or purge systems are being used.

• Check piping for leaks. • Clear piping of sediment or other foreign matter. • Clean the Transmitter process heads, including the barrier diaphragms.

5.3 Inspecting and Cleaning Barrier Diaphragms Depending on the characteristics of the process medium, sediment or other foreign particles may collect in the process head cavity/chamber and cause faulty measurement. In addition, the barrier diaphragm(s) in the Transmitter meter body may become coated with residue from the process medium. The latter is also true for external diaphragms on flange-mount and remote seal type Transmitters. In many cases, you can readily remove the process head(s) from the Transmitter meter body to clean the process head cavity and inspect the barrier diaphragm(s). For flange-mount and remote seal diaphragms, you may only need to run a purge line in the tank to rinse off the face of the diaphragm(s). The following procedure comprises the general steps for inspecting and cleaning barrier diaphragms. You may have to modify these steps to meet your particular process or transmitter model requirements. Figure 21 shows an exploded view of a Differential Pressure (DP) Transmitter meter body for reference. For disassembly/reassembly purposes, Gauge Pressure (GP) and Absolute Pressure (AP) Transmitters are similar.

It is recommended that you remove the Transmitter from service and move it to a clean area before disassembling it.


Figure 21 – DP Transmitter Head Disassembly

1. Close all valves to isolate the Transmitter from the process.

2. Open the vent in the process head to drain fluid from the Transmitter meter body, as necessary.

6 Calibration

6.1 Recommendations for Transmitter Calibration The ST 800 Pressure Transmitter does not require periodic calibration to maintain accuracy. Typically, calibration of a process-connected Transmitter will degrade, rather than augment the capability of a smart Transmitter. For this reason, it is recommended that a Transmitter be removed from service before calibration. Moreover, calibration will be accomplished in a controlled, laboratory-type environment, using certified precision equipment.

6.2 Calibration Procedures For a Transmitter operating in analog mode, you must calibrate its output signal measurement range using any compatible hand-held communicator or a local display. One calibration option is to use the Honeywell Smart Field Communicator (SFC). Refer to the Smart Field Communicator Operating Guide, 34-ST-11-14 for calibration procedures. Calibration information and procedures for a Transmitter operating in the HART/DE mode are provided in the ST 800 Series HART/DE Option User’s Manual, document number 34-25-25-35, Section on “Calibration.”


7 Troubleshooting

7.1 Overview Troubleshooting involves responding to error messages, primarily displayed by the MC Toolkit. Error messages that may occur on the Transmitter’s local display are fairly self-explanatory and intuitive. However, this section covers the diagnostic messages that indicate critical conditions. Other than the critical conditions, additional detail is not provided. If you require assistance, contact your distributor or Honeywell Technical Support. All other messages are covered by the MC Toolkit Users’ Manual.

7.2 Critical Diagnostics Screens When a Critical Diagnostic is present in the Transmitter, the Advanced Display will show one or more of the screens pictured in Figure 28. These screens will be inserted into the normal screen rotation and displayed between the user-defined operator screens. A description of the diagnostic conditions is given Table 20, along with suggested actions for resolving the problem.

Meterbody fault Electronics Module fault Meterbody Comm fault

Figure 28 – Local Display Fault Diagnostic Conditions

The Basic Display will display the message CRITCAL FAULT on the top line of the LCD and the appropriate diagnostic text on the lower line.

7.2.1 Fault Conditions and Recommended Corrective Actions

Table 20 – Fault Conditions and Recommended Corrective Actions.

Condtion Analysis Recommended Corrective

Action Meterbody fault. A critical failure has been detected in the Meterbody

Use a HART, DE, or FF communicator to read the detailed status information from the transmitter. Refer to the appropriate communicator manual to get more information about the possible causes of the failure.

Cycle power to the Transmitter. If the problem continues to occur, replace the Meterbody.

Electronics Module Fault. A critical failure has been detected on the HART, DE, or FF Electronics Module.

Use a HART, DE, or FF communicator to read the detailed status information from the transmitter. Refer to the appropriate communicator manual for more information about the possible failure causes.

Cycle power to the transmitter. If the problem continues to occur replace the Electronics Module.


Meterbody Comm fault. Communications between the Meterbody and the Electronics Module has failed.

This could be the result of a failure on either of these modules or the cable that connects them. Use a HART, DE, or FF communicator to read the detailed status information from the transmitter. Refer to the appropriate communicator manual to get more information about the possible causes of the failure.

Check the ribbon cable that connects the Meterbody to the Electronics Module. Make sure that the cable is securely plugged into the Electronics Module. Make sure that all pins are plugged into the connector (i.e., make sure that the connector is not offset in a way that leaves some pins unconnected). Cycle power to the transmitter. If the problem continues to occur replace the Electronics Module. If this does not fix the problem, replace the Meterbody.

A4. Marking ATEX Directive General:

The following information is provided as part of the labeling of the transmitter: • Name and Address of the manufacturer • Notified Body identification: DEKRA Quality B.V., Arnhem, the Netherlands

• For complete model number, see the Model Selection Guide for the particular model of

pressure transmitter. • The serial number of the transmitter is located on the Meter Body data-plate. The first two

digits of the serial number identify the year (02) and the second two digits identify the week of the year (23); for example, 0223xxxxxxxx indicates that the product was manufactured in 2002, in the 23 rd week.

Apparatus Marked with Multiple Types of Protection The user must determine the type of protection required for installation the equipment. The user shall then check the box [�] adjacent to the type of protection used on the equipment certification nameplate. Once a type of protection has been checked on the nameplate, the equipment shall not then be reinstalled using any of the other certification types.

WARNINGS and Cautions: Intrinsically Safe and Non-Incendive Equipment:

WARNING: SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR USE IN HAZARDOUS LOCATIONS.

Explosion-Proof/ Flameproof: WARNING: DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE MAY BE PRESENT

Non-Incendive Equipment:

WARNING: DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE MAYBE PRESENT All Protective Measures:

WARNING: FOR CONNECTION IN AMBIENTS ABOVE 60oC USE WIRE RATED 105oC


A.5 Conditions of Use” for Ex Equipment”, Hazardous Location Equipment or “Schedule of Limitations”:

Consult the manufacturer for dimensional information on the flameproof joints for repair.

Painted surface of the ST800 may store electrostatic charge and become a source of ignition in applications with a low relative humidity less than approximately30% relative humidity where the painted surface is relatively free of surface contamination such as dirt, dust or oil. Cleaning of the painted surface should only be done with a damp cloth.

Flame-proof Installations: The Transmitter can installed in the boundary wall between an area of EPL Ga/ Class I Zone 0/ Category 1 and the less hazardous area, EPL Gb/ Class I Zone 1/ Category 2. In this configuration, the process connection is installed in EPL Ga/ Class I Zone 0/ Category 1, while the transmitter housing is located in EPL Gb/ Class I Zone 1/ Category 2. Intrinsically Safe: Must be Installed per drawing 50049892 Division 2: This equipment is suitable for use in a Class I, Division 2, Groups A, B, C, D; T4 or Non-Hazardous Locations Only. The enclosure is manufactured from low copper aluminium alloy. In rare cases, ignition sources due to impact and friction sparks could occur. This shall be considered during Installation, particularly if equipment is installed a Zone 0 location. If a charge-generating mechanism is present, the exposed metallic part on the enclosure is capable of storing a level of electrostatic that could become incendive for IIC gases. Therefore, the user/ installer shall implement precautions to prevent the build up of electrostatic charge, e.g. earthing the metallic part. This is particularly important if equipment is installed a Zone 0 location.
